Compare the pressure of the same liquid at the bottom of the glass and at the bottom of the bucket
Compare the pressure of the same liquid at the bottom of the glass and at the bottom of the bucket, as well as the forces with which the liquid acts on them.
The pressure on the bottom of a glass and a bucket of the same liquid at the same height will be the same. Because the pressure of the liquid is determined by the formula P = ρ * g * h, where ρ is the density of the liquid, g is the acceleration of gravity, h is the height of the liquid. We see that the pressure depends only on the density of the liquid and the height. Since the liquid is the same and the height is the same, the pressure will also be the same. But the force with which this liquid will act on the bottom will be different. Dependence of force and pressure P = F / S, where F is the force, S is the area to which this force is applied. F = P * S from the formula it is seen that with the same pressure, the force will be greater where the area S is larger. The force on the bottom of the bucket will be greater as the area of the bottom of the bucket is larger.
